Every forward-dated tender Canadian healthcare GPOs publish, in one place — plus where to watch the ones that don't publish a calendar at all.
Mohawk Medbuy is the only Canadian healthcare GPO that publishes a forward RFP calendar. It does it as PDFs linked off its vendor page, not indexed anywhere. This tool reads them directly, so the dates below come from MMC's own document — but MMC labels them tentative, and they move.
These bodies publish live tenders only — no forward calendar exists to read. Rather than invent dates, this is the registry: what each one covers, where it posts, and what to do about it.
